3.8
bend stiffener
ancillary conical shaped component, which locally supports the pipe to limit bending stresses and curvature of the pipe to acceptance levels
NOTE Bend sofleners can be either attached 10 an end fitting or a support structure where the flexible pipe passes through the bend stiffener
3.9
bending stiffness
ability of a flexible pipe to resist deflection when subtected to bending loads at constant tension, pressure and temperature
3,10
bonded pipe
flexible pipe in whh the steel reinforcement is integrated and bonded to a vulcanized elastomeric material where textile material is included in the structure to obtain additional structural reinforcement or to separate elastomeric layers
3.11
burst disk
weak points in the outer sheath designed to burst when the gas pressure in the annulus exceeds a specified value
NOTE The weak poini is induced by reducing the thickness of the sheath over a localized area
3.12
carcass
interlocked metallic construction that can be used as the innermost layer to prevent, totally or partially, collapse of the internal pressure sheath or pipe due to pipe decompression, external pressure, tensile armour pressure. and mechanical crushing loads
NOTE The carcass may be used externally to protect the external surface of the pipe
3.13
choke-and-kill line
flexible pipe jumper located between choke manifold and blow-out preventer
3.14
connector
device used to provide a leak-tight structural connection between the end fitting and adjacent piping
NOTE Connectors inckide bolted flanges. damped hubs, aid proprietary connectors They may be designed for diver. assisted makeup or for diverless operation using either mechanical or hydraulic apparatus.
3.15
crossover
flexible flowline crossing another pipe already laid on the seabed
NOTE The underlying pipe may be a steel pipe or another fleiuble pipe It may be required to support the overlying pipe to prevent overbending or aushing of the new or existing pipes
3.16
design methodology verltication report
evaluation report prepared by an independent verification agent at the time of an initial review, for a specific manufacturer, confwrning the suitability and appropriate limits on the manufacturer’s design methodologies
NOTE This report may include occasional amendments or revisions to address extensions beyond previous limits or revisions of methodologies
3.17
design pressure
minimum or maximum pressure, inc)usive of operating pressure, surge pressure including shut4n pressure where applicable, vacuum conditions and static pressure head
3.18
dynamic application
flexible pipe configuration that is subjected to loads that vary in time, or whose deflections or boundary cOnditions vary in time
3.19
end (thing
mechanical device which lorms the transition between the flexible pipe body and the connector whose different pipe layers are terminated in the end fitting in such a way as to transfer the load between the flexible pipe and the connector
320
fistiscaling
tendency of one tensile armour wire edge to lift off of the underlying layer because of deflection or incorrect twist deformation during armour winding
3.21
flexible flowline
flexible pipe. wholly or ri part, resting on the seafloor or buried below the seafloor, and used in a static apphcation
NOTE The term lloene is used this document as a generic term for flexible flowlines
3.22
flexible pipe
asserrbly of a pipe body and end fittings where the pipe body is composed of a composite of layered materials that form a pressure-containing condu and the pipe structure allows large deflections without a significant increase in bending stresses
NOTE Normally the pçie body is built up as a composile stnxture composed at rnetalic arid polymer layers The term ‘pip& is used m this document as a generic term for flexible pipe
3.23
flexible riser
flexible pipe connecting a platformlbuoylship to a flowline, seafloor installation, or another platform where the riser may be freely suspended (free. catenary), restrained to some extent (buoys, chains), totally restrained or enclosed in a tube (I- or J4ubes)
3.24
independent verification agent
independent party or group, selected by the manufacturer, who can verify the indicated methodologies or performance based on the technical literature, analyses, and lest results and other information provided by the manufacturer
NOTE The agent is also caled upon to witness some measurements and tests related to material qualifrcabon
3.25
insulation layer
additional layer added to the flexible pipe to increase the thermal insulation properties, usually located between the outer tensile armour layer and the outer sheath
3.26
intermediate sheath
extruded polymer layer located between internal pressure and outer sheaths, which may be used as a barrier to external fluids in smooth bore pipes or as an anti-wear layer.
